Oral and maxillofacial reconstruction with modified pectoralis major myocutaneous flap technique

Pectoralis major myocutaneous flap has been used generally in functional and cosmetic reconstruction of and maxillofacial defects due to trauma or cancer surgery. The flap has many advantages with its relatively high success rates, but according to many authors, the complication rates of partial or total necrosis of skin paddle has been reported from 6% to 28% of cases. To reduce these complication rates, in 1990. Marx and Smith introduced new technique that preserved a greater vascular pedicle in flap s base with their higher success rates than those of conventional technique. By modifying Marx and Smith s new methods, authors also have achieved good clinical results and suggest its general use in head and neck reconstruction, especially in cases of osteoradinecrosis or patients who have known vascular disease, or who scheduled postoperative adjuvant radiotherapy.
